Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed November 4, 1915. Serial No. 59,610.

To all whom it may concern:

Be it known that I, PILADE BARDUCOI, a subject of the King of Italy, residing at Naples, Italy, have invented certain new and useful Improvements in Machines for Drawing Out Macaroni or like Alimentary Pastes, of which the following is a specificat-ion.

This invention relates to improvements in machines for drawing out pastes, particularly in the machines intended for the manufacture of macaroni or like pastes drawn out in form of long threads or tubes, in which the dies are located partially or totally out of the projection of the area of the receiver in which the fresh paste is contained in order to have the threads or tubes of paste spread out on a larger extent than the area of said receiver.

This invention has for its object a particular construction and -mounting of the part arranged between the receiver and the dies by means of which the paste is distributed in a uniform manner on the dies. Furthermore the dies as well as all the parts coming in contact with the paste may be easily inspected when required for cleaning or removing them.

In the annexed drawings some constructions of the machine are illustrated by way of example, and :Figure 1 is a general view of the machine, Fig. 2 is another general view of the same, Fig. 3 is a plan view of a type of machine in operative position, Fig. 4: is a vertical sectional view on mm, Fig. 3, Fig. 5 is a vertical sectional view on g Fig. 3, the distributing block being raised, Fig. 6 is the plan view of another type, Fig. 7 is the vertical sectional view on a=m, Fig. 6, Fig. 8 is the vertical sectional view on yy, Fig. 6, the distributing block being raised, Fig. 9 is a vertical sectional View on zz of Fig. 6, illustrating details in enlarged scale, Fig. 10 shows a portion of Fig. 9 in enlarged scale, Fig. 11 is an inverted view of the distributing block having one of the die plates in place and another one removed, Fig. 12 is a view corresponding to Fig. 7 and showing another construction.

It is assumed for the description of the apparatus according to this invention that the same is mounted in a vertical machine under a cylindrical receiver in which the fresh paste is fed, but obviously it may be mounted in horizontal machines and in connection with receivers of any other shape.

The apparatus comprises a base 1 secured by way of example to two columns 2 of the machine, the receiver 3 being mounted on one of said columns in such a way as to be capable of being rotated out of operative position for filling it, cleaning or the like (Figs. 1 and 2).

The base 1 is shaped in form of a cup in which the distributing block 1 is arranged, said cup being open at the lower portion and having an edge 5 on which the dis tributing block rests by its side on which the die plates are located.

A frame 6 may be arranged on the edge 5, this frame being divided in sections each of which corresponds to one section of the dies, alternatively it may be provided with intermediate ribs. In any case the die comprises a number of plates 7 suitably holed and arranged either parallel to each other (Figs. 3, 41 and 5) or in endwise relation to each other (Figs. 6-11) or finally the die may result from a series of circular or polygonal plates (Fig. 12). According to the number and arrangement of said plates the die will have given shape and extent, said extent being larger than the area of the receiver in order that the threads or tubes of paste may be spread out to the required extent.

In order to distribute 011 the dies the paste which has been driven out from the receiver 3 because of the pressure exerted by means of the piston 3' and rod 3" controlled by a hydraulic pressure cylinder 3', the distributing block is provided at its lower portion with a plurality of recesses 8 corresponding to the plates 7 of the die and with a single upper chamber 9 this chamber communicating directly or not with the receiver 3.

The distributing block is provided with passages leading from chamber 9 to chambers 8 so that the paste is uniformly distributed on the whole extent of each section of the die.

According to the construction shown in Figs. 3, 1, and 5, passages 10 are made in the distributing block, said passages diverging from upper to lower end in order to cause the chamber 9 to communicate with all the chambers 8 and between said passages 10 ducts 11 are left which communicate with by means of holes 10.

each other andare intended to allow of establishing a. circulation of hot water in order to heat the paste and maintain it in the required condition of fluidity, while passing through the passages 10.

According to the construction shown in Figs. 6, 7, 8, and 12, the upper chamber 9 communicates with passages 9 which extend on the whole length ofthe die and lead to the chambers 8 located above the die plates In order to obtain a uniform pressure on the die plate the sectional areas of said holes are increasing from chamber 9 toward chambers 8. The paste is suitably heated by causing hot water to circulatein the ducts 11.

' VVhatever' the construction of the distributing block may be, it is secured to two arms 12 arranged with their axes displaced sidewise with respect to the middle plane of the distributing block said arms being pivoted in'bearings 13 of the base 1 and be ing hollow in order to establish a circulation of hot water in the distributing block. One of said arms 12 is solid with a toothed segment 1 engaged with a screw 15 operated'by means of the handwheel 16 so that the distributing block may be raised easily and turned out as shown in Figs. 5 and 8,

in order to replace the die plates or to clean the parts contacting with the paste.

The die sections 7 may have any required shape and are usually constituted by plates provided with suitable holes; they are so mounted on the distributing block as to shut each the'mouth of one of the chambers 8 and rest on the edge or on the ribs of the frame 501' 6 (Fig. 11). In any case said die plates rest on a part secured to the base of the machine.

In order to prevent the plates 7 from being removed from the distributing block when this latter is raised as shown in Figs. 5 and 8, said plates are secured to the block in any suitable way, as by means of hooks 1T} pivoted on the block and capable of grasping the edges of the plates 7 (Fig. 1) or by means of stops 18 (Figs. 10 and 11).

In many cases it is advisable to provide the ends of the distributing block with a. device intended to force the distributing block on the frame 5 or'6 of its base in order to obtain a good tight joint between the mouths of chambers 8 and the edges of the corresponding dies 7.

One construction of said apparatus is shown by way of example in Fig.7 in which at the ends of the distributing block are arranged spindles 19 capable of endwise motion but prevented from rotating with regard to the base, said spindles being controlled by screws cut in the holes of sleeves 20 which; encircle said spindles and are toothed on their outer surface. Said sleeves are actuated by means of a gearing not shown mounted on the shaft 19 which is operated by means of the hand wheel 22. Each of said spindles 19 is provided with a head 2-3 having a tooth 23 under which a cotter 21 is inserted. This cotter 24- engages by means of the tooth er the edge of the distributing block so that by operating the hand wheel 22 the distributing block and the die plates may be forced against the base.

The operation of the machine is as follows: The paste supplied in the receiver 3 in any suitable way is forced by means of the piston 3 in the chamber 9 of the distributing block, thence it passes through the passages 10 or 9 and holes 10 and is distributed in a uniform manner on the whole extent of the dies, the pressure exerted on the dies being wholly sustained by the lower frame and intermediate ribs solid with the standard of the machine. By means of the device described the drawing out of the paste is effected in the best conditions as owing to the construction of the distributing block it is possible to distribute uniformly the paste on the dies without requiring the differential heating of the paste and the die sections are so mounted as to rest directly on a frame of the standard their edges being preferably engaged between the distributing block and the lower frame. Furthermore owing to the mounting of the distributingblock it is possible to have easy access to the die sections and to all parts which come in contact with the paste, this being a very useful feature of the arrangement according to this invention as it insures the regular operation of the same.

What I claim as my invention and desire to secure by U. S. Letters Patent is 1. In an apparatus for drawing out pastes. in combination a receiver in which the paste is forced, a single removable block having an upper chamber communicating with the mouth of said receiver when said block is in operative position, lower chambers in said block extending beyond the projection of the area of the receiver, passages in said block connecting the upper chamber with the lower chambers to distribute the paste in said lower chambers, dies at the mouths of said lower chambers, a member carrying said block and means in said member on which rest the edges of the dies when the block is in operative position.
